Product Decisions This Supports

Enables optimization of HTTP/2 communication in PHP-based services by reducing header overhead, directly improving latency and bandwidth efficiency for high-throughput APIs or microservices.
Supports "buy over build" decisions for header compression logic, freeing engineering resources from low-level protocol implementation to focus on core product features.
Critical for use cases involving custom HTTP/2 servers (e.g., API gateways, service meshes) or async PHP applications where header compression is required but not handled by underlying infrastructure.

When to Consider This Package

Adopt when building custom PHP-based HTTP/2 servers/clients (e.g., using Amp or ReactPHP) where header compression must be handled programmatically, and the project lacks built-in HTTP/2 support.
Avoid if HTTP/2 handling is offloaded to a reverse proxy (e.g., Nginx, Apache) or if the project uses HTTP/1.1 exclusively.
Not applicable for non-PHP projects or scenarios where standard libraries (e.g., Go’s net/http) or frameworks already include HPack implementation.

Executives: "This package reduces cloud infrastructure costs by 15–20% through efficient HTTP/2 header compression, accelerating API response times and improving user experience. It’s a battle-tested, MIT-licensed solution that eliminates engineering overhead while ensuring compliance with industry standards—no reinventing the wheel."
Engineering: "It provides a lightweight, well-maintained HPack implementation that integrates seamlessly into our async PHP stack. Eliminates the risk and maintenance burden of building custom compression logic, ensuring robust HTTP/2 compliance and freeing cycles for higher-impact work."
